Thought this was informative, so here it is. http://www.ipmsstockholm.org/magazine/2004/10/stuff_eng_tech_ca_glue.htm I love these adhesives...... BAM, DONE! Used it to fix my glasses (spectacles ) tonight. I let it dry for 20 minutes and was reading up on how humidity affects this stuff as an accelerator. With the adhesive on the edge of the glass, it created a white "smoke" on the edge of glass as it cured and did it's thing. I kept holding the glasses firmly together for 15 minutes. (not 60 seconds) OK, so after reading about humidity accelerating the cure, I boiled some water in the microwave, then put my glasses in there with the cup of water and shut the door, trapping the heat and humidity.................... The glasses fogged up again with that white "smoke" looking stuff on the edges. I guess even after 10+ minutes of air cure, the glue hadn't fully cured out. Interesting............ Anyway, just some food fer thought. My choice of cyanoacrylate adhesive is made by Bob Smith Industries......... they have super thin cyanoacrylate adhesives and super thick gap filling adhesives... Not to mention their epoxy adhesives. I buy mine at a True Value Hardware store where it's private labeled with the store name. I like this stuff a lot more than the well known brands Like Krazy Glue and Locktite because it comes in thin, thick, gap filling and super thick, for different purposes...... plus they carry accelerators and non stinky versions of their products. I think it also found at hobby stores. Jones make a lot of adhesives for model construction purposes. If ya get some on your finger, .....don't stick your finger in your eye......... you know, just read the instructions. These things are faster that you are.
